Q. Kamal likes to go on canoe trips, and on each trip he purchases oars to keep as souvenirs. His collection of oars is organized by decade and type of wood.

\begin{tabular}{|c|c|c|}

\newline

\hline & Spruce wood & Ash wood \\

\newline

\hline

2010

\end{tabular}

\newline

What is the probability that a randomly selected oar was not purchased in the

2010

s and was not made from spruce wood?

\newline

Simplify any fractions.

\newline

\square

Calculate Total Oars: Total oars from $2010$ s: $2$ (Spruce) + $2$ (Ash) = $4$ . Total oars from $2020$ s: $5$ (Spruce) + $4$ (Ash) = $9$ .
Identify Oars from $2020$ s: Total oars not from $2010$ s: $9$ (from $2020$ s).
Calculate Oars Not from $2010$ s: Total oars not made from spruce wood: $2$ ( $2010$ s, Ash) + $4$ ( $2020$ s, Ash) = $6$ .
Calculate Total Oars: Total oars: $4$ ( $2010$ s) + $9$ ( $2020$ s) = $13$ .
Identify Oars Not from $2010$ s and Not Made from Spruce Wood: Oars not from $2010$ s and not made from spruce wood: $4$ ( $2020$ s, Ash).
Calculate Probability: Probability = $\frac{\text{Number of oars not from 2010s and not made from spruce wood}}{\text{Total number of oars}} = \frac{4}{13}$ .
